Funcall

Change-funcall

Modifying constructor for funcall structures.

Syntax

(change-funcall x 
                [:name <name>] 
                [:args <args>])

This is an often useful alternative to make-funcall.

We construct a new funcall structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

This is an ordinary change- macro introduced by fty::defprod.

                           (:args . funcall->args))

                         'nil))
